This is a negative B&W of 9 x 10-minute subs from the Sky90/M26C average combined. There a bunches of hot pixels, green splodges from bright stars, dust bunnies and a slightly obtrusive plane trail all because of the average combine (used to preserve the asteroids which you would lose with SD mask stacking). I have arrowed the other 7 asteroids I could see in the field. This is so much fun I think I might have another go next outing.
